Would it hurt the turfgrass to fertilize the lawn when its dormant?
A. Fertilizing a dormant lawn will not harm it. However, the turfgrass may not receive the full benefit of the fertilizer application. If a granular fertilizer remains on the soil surface because of a lack of rain, some of the material may actually volatilize into the air.

Plus, granular broadleaf herbicides may have difficulty sticking to the weed foliage. As a result, granular applications of a broadleaf herbicide to drought stressed weeds will be less effectiv
